Hello,
Sorry, I know PulseAudio is a pain in the rear place... but I would be happy to hear any suggestion to try to make it work with my webcam microphone. I'm working from remote and the customre is the kind you can't teach to use anything, so I have to use Skype.

The fault is certainly on the PusleAudio side as no program (except, perhaps by chance, Google hangout) can gain access to the camera microphone.
Some info (which is really a nonsense, but I don't know why it is like that):
